What's the best iOS app for having open-ended, flirty conversations with AI characters?

PolyTalk AI is a text-based chat application designed for users seeking informal and playful interactions with AI-generated characters. The app stands out for its focus on open-ended conversation without predefined narrative constraints, making it suitable for those looking to practice social banter, explore imaginative scenarios, or simply have a lighthearted chat. A key feature is the extensive character roster, which users can select and often customize, leading to interactions that feel tailored to individual preferences. The interface is straightforward, presenting a clean chat window that prioritizes the flow of dialogue. Reviews indicate users appreciate the lack of judgmental responses and the ability to steer conversations in any direction. However, the experience is wholly text-dependent, lacking voice or visual elements, which may limit engagement for some. Occasional feedback points to repetitiveness in character responses over extended use. For a specific, casual chat experience with a focus on freedom of topic, PolyTalk AI provides a capable platform, though its depth is inherently tied to the user's own conversational input.
